The Cisco® Wireless IP Phone 8821-EX is a ruggedized, resilient, and secure 802.11 wireless LAN handset that delivers cost-effective, on-premises, comprehensive Voice over Wireless LAN (VoWLAN) communications for the highly mobile in-campus worker.

Availability Planned Q4 CY 2018

The 8821-EX builds upon all of the features offered by the Cisco Wireless IP Phone 8821 and adds nonsparking support for temporary exposure within potentially combustible environments. It is ATEX Class I, Zone 2 and CSA Class I, Division 2 certified. ATEX Zone 2 is defined as an area in which an explosive gas atmosphere is not likely to occur in normal operation and, if it does occur, is likely to do so only infrequently and will exist for a short period only (for example, less than 10 hours per year). Similarly, CSA Class I is a location where a quantity of flammable gas or vapor sufficient to produce an explosive or ignitable mixture may be present in the air. Division 2 is a location where a classified hazard does not normally exist but is possible under abnormal conditions. Zone 2 is an area in which an explosive gas atmosphere does not normally exist.

While the 8821-EX is sleek and lightweight, the design is hardened for users. It is Ingress Protection standard (IP67) rated and is sealed for protection against dust, splash, and water. The device is also MIL-STD-810G tested, with a dozen drops onto concrete from heights of up to 6 feet (1.8m), to help ensure shock resistance and avoid breakage if dropped.

The 8821-EX enhances security and simplifies configuration management. Stronger encryption is supported for certificate management and policies enablement with the EX model’s support of Secure Hash Algorithm 2 (SHA-2). Simple Certificate Enrollment Protocol (SCEP) eases IT administration by enabling automatic certificate management on the device.

End users will enjoy a larger, higher-resolution color display (Figure 1) and a user experience that is common with Cisco IP Phone 8800 Series desk phones. In addition, roaming between access points within the campus will support more seamless voice communications with the 8821-EX’s support of Fast Transition (802.11r). This protocol was specifically designed for mobile Voice over IP (VoIP) communications devices within Wi-Fi networks. Bluetooth is supported for the user’s choice of third-party wireless headsets and adds freedom by untethering the user from the handset.

The 8821-EX supports Cisco and third-party XML applications such as push-to-talk.

Note:    For information about the desktop charger, multicharger, and carrying cases, refer to the Cisco Wireless IP Phone 8821 Accessory Guide.

Cisco IP phones are covered by a Cisco standard 1-year replacement warranty. A Cisco Smart Net Total Care™ optional service agreement is available for the Cisco Wireless IP Phone 8821-EX, desktop charger, and multicharger only, not for other accessories, such as batteries and carrying cases. The 8821-EX battery has only a 90-day warranty.

●   This product is not a medical device and may use an unlicensed frequency band that is susceptible to interference from other devices or equipment.

●   A moist cloth can be used for simple cleaning. For the healthcare environment, Caviwipes and Saniwipes are the popular recommended choice for thoroughly cleaning the phone. Caviwipes and Saniwipes contain up to 17 percent isopropanol. Any cleaning solution containing a higher degree of isopropanol, including pure isopropanol, or an alternate alcohol-based liquid, could potentially damage the phone. Refer to the Cisco Wireless IP Phone 8821 User Guide for detailed instructions.

●   Carry cases can help protect the phone and provide drop protection.

●   The Cisco Wireless IP Phone 8821 was tested under controlled laboratory conditions with a rating of IP67 under IEC standard 60529. Splash, water, and dust resistance are not permanent conditions, and resistance might decrease as a result of normal wear. Users are expected to take care of the Cisco Wireless IP Phone 8821 and should not deliberately expose the device to a hostile environment of dust, splash, or water immersion. Do not attempt to charge a wet Cisco Wireless IP Phone 8821 or dock it on a desktop or multicharger. Refer to the Cisco Wireless IP Phone 8821 User Guide for cleaning and drying instructions. Liquid damage to the Cisco Wireless IP Phone 8821 is not covered under warranty.

●   Use only batteries that are approved by Cisco. Use of unapproved batteries might be dangerous, and will invalidate the warranty on your phone.
